Specification of Letters Patent.

-Patented June 25, 1907.

Application filed February 11, 1902. Serial No. 93,522.

To (all whom it may concern:

Be it known that I, FRANK SCHAFER, or"

the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Machines for Making Tubes, of which the following is a specification.

My invention consists of an improved machine for making tubes, the object being to provide in a single structure devices for forming a tube having angular sides, for gluing the same, for applying frictional matter to one of the sides thereof, for printing upon a side of the tube, and lastly for cutting the tube into lengths so as to serve as the tube for match boxes.

It further consists of novel details of construction, all as will be hereinafter fully set forth and particularly pointed out in the claims.

Figure 1 represents a side elevation of the front end portion of a machine constructed in accordance. with my invention. Fig. 2 represents a side elevation of the rear end ortion thereof, said figures being separate for convenience of construction. .Flg. 3 represents a top plan view of the portion of the machine shown in Fig. 1. Fig. 4 represents a top plan view of the portion of the machine shown in Fig. 2. Figs. 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 18 19, and 20 represent vertical sectional views, taken respectively on the lines 55 to 2020, both inclusive, of Figs. 1, 2, 3 and 4. Fig. 21 represents an end elevation at the rear end of the machine, showing the cutting devices in detail. Fig. 22 represents a horizontalsection taken on the line 2222 of Fig. 21 Fig. 23 represents a plan of the wheel for applying the glue by which the sand or other friction material is caused to adhere to the box. Fig. 24 represents a section thereof. Fig. 25 represents a perspective view of the 'fin ished tube after being cut into sections, the printed matter being omitted. Fig. 26 represents a modification of the ink feeding devices for printing rollers. Fig. 27 is an edge view on an enlarged scale of the wheel for applying glue shown in Fig. 23. Fig. 28 represents a side elevation of a portion of said wheel in the act of applying the glue.

of the machine, upon which the operative parts thereof are mounted, said tables bein conveniently secured together by means the strips 3. As the supports and bearings for the different rollers and other devices which. act upon the tube as it passes through the machine in the course of formation are of well known construction and clearly shown in the drawings, I will for the sake of brevity not refer specifically thereto, but only to the parts sup )orted thereon, The roller 4 carrying the roll of cardboard, strawboard or other material of which the tube is to be formed is mounted at the front end of the machine and the strip taken therefrom is passed through the different rollers and other devices to the other end of the machine where it passes between the feed rollers 6 suitably driven, which draws the material through the machine in the course of the formation of the tube. roller 4 the material first passes between the grooved roller 7 and the scoring disks 8 (Fig. 5), the shaft of the latter being driven by the gearing hereinafter described. These disks Sscore and bend the strip on the lines -9 shown in Fig. 3. Then the'scored and bent strip passes between the rollers (Fig. 6) 10 and 11, the roller 11 bein situated over a longitudinal former 12, the front end of which is located between said rollers 10 and 11 and the scoring devices. The rollers 10 are situated at an incline on opposite sides of the former and thus bend the strip to the posi tion shown in Fig. 6 to guide it to the next set of rollers (Fig. 7), consisting of vertical side rollers 13 and horizontalupper roller 14 which guide the strip to the next set of rollers with the long sides thereof parallel and hu ging the sides of the former, while the lower edges of the strip project below the lower edge of the former, it being noted that on one side the strip projects below the lower edge of the former a little greater distance than on the other. The short side of the strip is then to be turned in to form the inner flap of the connecting flaps of the tube.

In Fig. 8 is shown the first step in bending in the inner flap. In this figure the vertical side rollers 15 and upper horizontal roller 16 are employed while below the former is an inclined roller 17 which bends the inner flap to the position shown in said FigI-S, while in Fig. 9 the position of the roller 18 that engages the inner flap is changed to horizontal and in con- After leaving the III nection with-the vertical side rollers 19 and upper horizontal roller 2f) the tube is held in position shownm' said Fig. 9. i

The next operation is the application of adhesive material to the outer surface of the inner flap. V This is applied by a disk 21 driven by mechanism-hereinafter described the former bends the outer flap partially upon the inner. In Fig. 13 is shown the last operation upon the tube before it leaves the forrner.- In this figure are the vertical rollers 27 on the sides of the former and the horizontal rollers 28 above and below the same, the lower horizontal roller pressing the adjacent faces of the flaps firmly together and cause them to adhere: After leavin the former the tube is first flattened out by being passed through the vertical rollers 29 shownin Fig. 14. In flattening out the tube it will be seen that the glued flaps are at the lower edge thereof and on the left hand side in the direction of its movement.

The next operation is the ap lication of the sand or other material, it eing noted that as the longcontinuoustube is finally cut into short sections'30, shown in Fig. 25,

it is desirable to apply the sand to a section onlythereof as shown at 31. To accomplish this I employ a wheel having a segmental periphery so as to touch the outer flap of the tube at intervals. I also serrate or notch the periphery of this roller 32 so'as to more effectively apply the glue and to prevent the glue from being pressed beyond the sides, of the roller as the glue is applied. By notching or serrating the periphery of the roll 32 so that its periphery is provided with a'series of intersecting grooves or channels, I am, 'as above pointed out, enabled to more effectively apply the glue.

the surface thereof and would be pressed be the periphery of the disk carries a supply of glue the same will be left upon the tube after the disk rolls cross the same. An end eleva tion of the glue applying devices is shown in Fig. 15, wherein the, tube is supported on one 'side by a vertical roller 33, while the glue roller 32 on a vertical axis is situated opposite the outer flap. Mounted-on the lue receptacle' 34 is a shaft 35 driven by mec anism hereinafter described and carrying a disk 36 .oft eg If this disk had asmooth periphery the glue would adhere to' geared to the printing rollers.

submerged in the glue and contacting with a disk '37 mounted on an inclined axis and Whichcontacts with the glue feeding roller 32. The shaft carrying the incline roller 37 is provided with the gears 38 and 39, the 7 latter meshing with the gear-40 on the shaft 35 and the former with the ear 41 rigid with the roller 32, whereby the isk 37 and roller '32 are driven. s

The next step is to apply sand or other fric- 7 tion material to the glued surfaces of the outer flap and the mechanism for accomplishing this is shown in elevation and partly in section in Fig. 17, it being noted that a sup ort 3nd guide 42 is situated in the rea118 l e applying mechanism to hold the traveling tube in the correct position, and it will be noted that supports of the nature shown in Fig. 16 can be placed at convenient points throughout the machine as found de- 5 sirable. Situated to one side and above the V path of the tube is a sand hopper43 having a s out 44 at its lower end adapted to deliver t e sand against the lower flap of the tube, a receptacle 45 being placed below thesame g in which the surplus sand accumulates. 'I prefer to employ an agitator to insure a continuous fiow of sand and this may consist-of a rod 46 having a flattened end terminating near the upper end of the spout 44 and being 5 geared to a shaft carrying a gearwheel 47 that is suitably driven as hereinafter described.

The next ste is the drying of the glue by which the san is held and to accomplish this, as shown in Fig. 18, I employ an air blast, the fan 48- delivering to a nozzle '49 extending longitudinally along the sanded flap, whereby the current of air is blown a ainst and dries the same. It is however found that/small particles of the sand will not adhere sufliciently, and I have arranged air blasts, shown in Fig. 18 just in the rear of the nozzle 49, said air blast beingformed by tubes 50 receiving their supply of air from the fan 48 and projecting a forcible current of air against the sand to blow away any of these small particles. Then t'he tube asses between the vertical guide rollers 51 efore passing to the printing mechanism, it being noted that the guide rollers 51 on the side of the tube'carrying the sand is shorter so as not to contact therewith. The printing rollers 52 (Fig. 20) are mounted on opposite sides of the tube and carried by vertical shafts 53 and are situated between the feed rollers 6, being the last set of rollers, and a set of feed rollers 54 situated also on o .posite sides of the tube. The rollers 6,-52 an 54 are mounted on vertical shafts suitably geared to each other and with the main driving shaft 55 by the gearing shown, and 'ink is fed to the rollers 52 by the small rollers 56, the shafts of which are The ink is applied to the inking rollers 56 by means of the inclined inking rollers 57 that contact also with the rollers 58 situated within the inking receptacles 59. The shafts of these rollers 58 are geared to a cross shaft 60, which by means of a shaft 61 is geared to the main driving shaft as shown in Fig. 4. It is from this shaft that the driving parts heretofore described are also driven, conveniently in the following manner: A chain or belt 62 is trained around a gear on the shaft 60 and around the gear 63 on the shaft 35 of the gluing mechanism shown in Fi 15. A chain or belt 64 is trained aroun another gear upon the shaft 60 and around the car 47 of the sanding mechanism shown in 1g. 17. A chain or belt 65 is trained around another gear of the shaft .60 and around a gear 66 on the shaft 67 carrying the gluing disk 21, while a chain or belt 68 is trained around another gear 69 on the shaft 67 around a gear on the shaft 70 carrying the scoring disks 8.

The last and final operation upon the tube is the cutting of the same into sections as shown in Fig. 25. This is accomplished by a reciprocatory knife 71 (Figs. 21 and 22) car ried by a slide 72 mounted in guides 73 on the uright end plate 74 of themachine. The

7 er ge of the knife 71 passes over the edge of the cutting plate 75, conveniently countersunk into the end plate 74 at the far side of the guide opening 76 through which the tube is fed. As the tube is fed continuously the gearing for reciprocating the knife 71 is so arranged that it makes a quick advance and return during the cutting o eration, so as not to impede the progress of t e tube, the same being secured y means of the gears 77 and 78 mounted eccentrically upon the shafts 79 and 80. The shaft 79 carries a crank disk 81 that is connected with the slide 72 by the pitman 82. .The shaft is geared to the main driving shaft 55 by a chain or belt 83.

It is understood that although I have shown a former rectangular in cross section, yet other shapes may be em loyed to form tubes of other cross sectional gures.

' It is not absolutely necessary in the organization of the machine that the lue for binding the flaps, or for causing the ictional material to adhere should be applied at the-various stages of the formation of the tube illustrated, as it is obvious that it could be applied at other stages without departing from the spirit of my invention, and further that various other changes could be made in the construction and arrangement of the parts so long as the equivalent of those shown are emlgloyed. 1
